Cystic fibroid degeneration. This patient presented to the emergency department with vaginal bleeding and lower abdominal pain. a CT following iv contrast administration shows demarcated regions of low density within the fibroid representing cystic degeneration (black arrow) with enhancing surrounding soft tissue (white arrow) . These features are in keeping with degenerative change of a uterine fibroid. The differential diagnosis includes a complex ovarian mass. b Sagittal T2 MRI demonstrates a large heterogenous mass (white arrow) arising from the fundus of the uterus (black arrow). Cystic areas of degeneration are demonstrated by areas of high signal intensity within the fibroid. Identifying a connection to the uterus is important in making the correct diagnosis
